Monomials and Polynomials and Factoring - BTC Style

 This is the topic I've been waiting for!  Why?  Well, it feels like multiplying, dividing, and factoring of polynomials lends itself really well to thin-slicing and now I have a much better handle on how to moderate thin-slicing lessons.  I am definitely not even close to being what I would say is "good" at it, but I'm getting better.

This is the first of many posts for this unit.  I anticipate a lot of reflection on my part!!

So, the first post is about preparation.  Though I heard this during a workshop at last year's BTC conference, I really learned it through experience.  You can prepare, but it will likely be all thrown out at some point.  So, don't over prepare.  Peter says that, regarding consolidation, experience is better than anticipation.  In other words, don't assume anything but be ready to respond to what the students demonstrate in the classroom.

So, in preparation of not preparing :) I decided to start by setting up a progression for the unit.  Here is what I came up with:

Multiplying Monomials

Multiplying a Monomial by a Polynomial

Dividing a Polynomial by a Monomial

Finding the GCF of Whole Numbers

Finding the GCF of Monomials

Factoring out a GCF from a Polynomial

Multiplying Polynomials

Factoring Quadratic Trinomials (only a=1 is required for Algebra 1, but I may be able to present trinomials with a prime leading coefficient)

Factoring a Difference of Squares

I feel like this progression makes sense and I can easily connect each topic to the next.

The next step was to create thin-slicing questions for each of these topics.  To thin-slice, each subsequent question should be similar in difficulty to the previous question, or add a new element.  I admit that I start with Chat GPT here.  I ask the program to create a set of 10 problems for a given topic that progresses with those parameters.  Once the set is created, I may modify it or just print it out and modify on my own.  It's important to remember that Chat GPT is not a mind reader and that reviewing the material is necessary!  That said, I have found it to be a great starting point.

Of course, I have modified my plan quite a bit before the first day.  Sometimes, we can overthink and just need to jump in!

I Finally Did It!!!

 I finally... FINALLY left a class feeling like it was great! 

As I have been slowly building my thinking classroom in Algebra 1, I have learned so many things that haven't worked.  What I've learned the most is really two things.  

First, have a well thought out plan.  One that includes how to launch a task and how to monitor the task. 

Second, be ready to throw that plan out the window.  I've done this a lot, usually because I've realize that my well thought out plan was not as well thought out as I envisioned.

I teach two sections of Algebra 1.  I always feel bad for the first group because of how much I modify for the second group.  Yesterday and today, I introduced my students to arithmetic sequences.  We started by making tables for the following sequence of pictures...



I learned from class #1 that I needed to clarify that there were THREE pictures here.  Who would've thought that this would be considered only ONE picture? 

So, students were asked to make a table to show the number of stars for each picture (picture #1, #2, etc.)  We went up to picture #3 and I added the number 57 to the "picture #" column.  Well, that was fun.  Most groups were able to answer the question using the patterns they saw in the first few rows but I realized that they were using the number 57 to get their answer:  (57*2)+1.  So, I then asked them to determine the number of stars in picture 57 based on the number of stars in picture #1.  Students were originally coming up with 3+2(57).  After some discussion and questioning from me, we were all able to figure out that it was 3+2(56).  Yeah!!

Then came the algebra.  I added "n" to the picture # column.  Audible gulps and sighs.  But, off they went and off they succeeded!

We changed up the picture and I asked them to repeat the process and they were quickly able to come up with the appropriate rule.

Consolidation came next. 

Fill in the blank:  ______ + ______ (n-1)

Students came up with "first number" and "change" which I defined as a "common difference."  So, off they went to answer thin-sliced problems to write the rule for the arithmetic sequence.  At this point, they were simply writing the expression ___ + ____ (n-1).  There was no equal sign.  There were no subscripts.  I eventually flipped it around and gave them the expression and they had to produce the sequence of numbers.  Success!!  Not only were they nailing it, they were claiming it was easy!

I did not use any vocabulary other than "common difference" and I didn't even emphasize it.  Next class, the students will pick this up again and we will expand to add geometric sequences.

I'm keeping my fingers crossed for two solid (or semi-solid) BTC lessons in a row.  That would be a record!

So Much to Learn!!!

 In July, I attended the Building Thinking Classrooms Conference in Phoenix, Arizona.  It was absolutely amazing, yet very overwhelming.  There is just so much to learn!  When I left the conference, I was feeling empowered about building my thinking classroom for Algebra 1 this year, instead of "dabbling" as I had done in the past.  I am now one month into the school year, and I have so much to learn!!

As luck would have it, I had another opportunity to attend a workshop with Peter Liljedahl at a local high school.  This opportunity came at the perfect time for me.  Though much of it repeated a lot of what I have seen and heard before, I now have some experience.  I would say that my practice has been, at best, hit or miss.  There are just so many nuances that I have been floundering over.  Attending this workshop has helped me to identify what I'm missing and what I can do to improve.

When I returned to school today, we were learning about slope.  I started with a task that I modified from a  Math Medic activity, which can be found HERE.  This allowed us to explore rates of change and we connected it to the slope of a line.  Our second task, with a new group (something I picked up in Friday's workshop), was focused on using the slope formula that students had learned last year.  They worked through the thin-sliced problems and it was great!  I was able to walk around and give help where needed.  I consolidated by doing the "sort these three problems" conversation, which was pretty quick, then we went off to take notes.  I am NOT doing the four quadrant notes at this point.  One of the best parts about this particular modality of instruction is that it is not necessary to go all in with all fourteen practices.  I am picking and choosing which ones work for me and my students and doing the four-quadrant notes is not in that list quite yet, never mind the fourth toolkit!

Thank you to Bethlehem High School and to Peter Liljedahl for another great workshop!  I'm sure we will meet again!

Introducing My Thinking Classroom

 I just started my 28th year teaching high school math and I had the best first day(s) ever!  I teach in a block schedule, so last week I had two classes on Thursday and three on Friday.  I am teaching AP Calculus BC and Algebra 1.

In my calculus class, students completed two tasks at the boards.  I modified two lessons from MathMedic. The first was to find an estimate for an instantaneous rate of change based on a free fall by Austrian Felix Baumgartner, starting with a video of his accomplishment.  Instead of completing the entire MathMedic lesson, I had the students use the graph from the lesson to come up with an estimate of his velocity 30 seconds into his freefall.  We discussed how to make the best possible estimate since a rate of change is (generally) over time.

In the second lesson, I used a graph that showed the velocity of a motorcycle over time and asked the students how far the driver (me) travelled.  They were able to determine that they had to find the area under the curve and were able to estimate using geometric shapes.

The two activities were designed to introduce them to differential and integral calculus and we had a discussion of what calculus is all about.



In Algebra, students started with The Tax Collector.  Then we did some housekeeping items and moved into The Answers Are.  Both activities, found in the book, were great!  Students were engaged, getting ideas from other groups and having some great conversations.  We debriefed after both activities.  I asked the students three questions.  First, why did we use dry erase boards and not paper?  Paper just feels too permanent so we all feel better when it's easy to erase things we don't want to keep.  Second, why were the groups created randomly?  Some good conversation here about getting to know others as well as my explanation that it goes beyond the social.  Sometimes our classmates simply understand something better or can explain it better than Mrs. Swift.  The third question was about standing up.  One young lady shouted out "blood flow!"  Awesome!  Yes, standing allows us to move a bit and gets our blood flowing.  That, in turn, means our brains are more engaged and we think better.



All in all, a great first day!

Building Our Thinking Classrooms

 It's been a VERY long time since we blogged.  My thoughts are that we got so turned around during the pandemic that it took a couple more years to feel like we are back on our feet.  This feels like a good time to get re-started with blogging about our classrooms.

Speaking of our classrooms, both Randy and I have really gotten excited about Peter Liljedahl's (@pgliljedal) book Building Thinking Classrooms and most of our blogging will be about our experiences creating and growing our own Thinking Classrooms.

Randy is still doing academic intervention for grades 3-6 at Greenwich Elementary School in Greenwich, NY.  In addition to this, he is co-teaching mathematics in a 4th grade classroom, where he and his partner teacher are beginning their second year with a thinking classroom.

I am still teaching high school mathematics at Saratoga Springs HS in Saratoga Springs NY.  This coming year I will be teaching AP Calculus BC and Algebra 1.  It is in my Algebra 1 classes that I am planning to implement the first two (two-and-a-half?) toolkits of a thinking classroom.

We were fortunate to have had the opportunity to attend workshops this past May in Connecticut with Peter Liljedahl as the facilitator.  The workshop I attended was focused on how to close tasks, which I found extremely helpful as I was getting better at giving tasks (especially thin-sliced tasks) but did not feel comfortable with this next step.  Randy (and his co-teacher) attended the workshop about assessment, and they found it very helpful.  

At the end of June/beginning of July, we traveled to Phoenix, Arizona to attend the 2nd Annual Building Thinking Classrooms Conference.  This was AMAZING for us!  We were able to speak with others who are just as excited as we are about this framework and got so many ideas that we are eager to put into action in our respective classrooms.

This upcoming year, in our BTC journey, Randy will be focusing on assessment and how to assess within the BTC framework and compare/contrast it to the more traditional forms of assessment and grading.  He is using the grading rubric provided by Tim Brzezinski (@TimBrzezinski) and Melisa McCain (@mccainm).  I am going to be focusing on tasks (creating/finding, launching, closing) and note-making.

So, this is what the 2024-2025 school year will look like in the Swift household.

2020 Thoughts and Quotes



"How's it going?"

What a loaded question right now!  If that's how you often greet people, you might want to rethink asking a teacher that one.  We might tell you.

The reality is that, for most of us, it is not going well.  This is a hell of a lot more work than I had anticipated, and I anticipated a lot of work!  I just spent my entire Sunday working.  From 8:30 in the morning to about 5pm, I did school work.  First I had to start by figuring out how to undo the damage I did last week.  I don't want to tell that story, but let's just say it ended with tears.  Then, once I figured out what I should do for this coming week (yes, I am only planning a week at a time, but that's better than the day-at-a-time I've been doing), I had to figure out what I was going to do, how I was going to do it, then get it all organized.  So, here I am, at the end of the day and back in my pajamas, finally winding down.  Just to get up early tomorrow and put it all into action.

Okay, enough whining.  I really don't want to whine about this.  I know I'm not the only person in this boat and that others have it worse than I do, so on to the positive.

I was at a meeting last week where we had to identify something positive that has come out of the last few weeks.  That was easy.  The first Friday before students were coming in, a colleague put out a frantic email asking for help on how to set up her computer with Zoom and Smartboard and all the other stuff.  No less than five teachers jumped to help her.  This experience has bonded us together, a faculty of 170 teachers, like nothing ever could.  Colleagues from all different parts of the building, and district, have jumped to help one another with even the smallest things.  One teacher taught me how to best set up my computer so I can work with all my students.  I was able to show that teacher how to use a certain software to get the kids to collaborate more from home.

So, though it's tough, and every single day is a struggle, there are some little victories and lessons and I'm planning to focus on those.  One day at a time!

Flipping 2020

 We haven't written anything in our blog for a very long time, but I thought this would be a good time to start again.  This coming year is going to be crazy!!  I am teaching AP Calculus BC, Algebra 2, and a class we call Topics in Algebra 2 for students who aren't quite ready for the full Algebra 2 curriculum.

Our school is starting on a hybrid plan.  Students are divided into two cohorts.  Cohort 1 will be in-building on Monday and Tuesday and Cohort 2 will be in-building on Thursday and Friday.  All will be learning from home for the other three days.  So, teaching will be more of an adventure than usual!

I have always wanted to explore flipping my classroom but have never felt like the time was right or that I had all the tools I needed to do it.  Well, I'm not sure if the time is right and I'm pretty sure I don't have all the tools I need, but I'm going for it anyway!  I work with a great (much younger than me) teacher who inspires me to try new stuff and I will be sharing "our" stories as well.  Caitlyn Gironda (givemeasine.blogspot.com) gives me a lot of great ideas and has made me a better teacher as a result.  It's so nice to have someone to brainstorm with and maybe, just maybe, I'll be able to pull this off.

I have purchased and read the book Flipping with Kirch by Crystal Kirch, which has given me a foundation upon which to build my flipped classroom.  She has so much to offer but I will be doing my best to keep it as simple as possible for both me and my students.  I have developed a simple version of the WSQ ("whisk") to use on Canvas (our district's choice for a learning management system) that I will be using with my two algebra courses.

To be honest, I am way more concerned about the structure and pace of my AP class.  The schedule we have gives us less contact time than I am used to and there have been no changes made to the course.  I will still be flipping the class but using the notes and assignments I have always used in the past.  I have a feeling that this class will be going full speed ahead right from go!

I have chosen to look at the year as an opportunity to try something new, probably more than one something, and that will (hopefully) keep me sane!
